Abstract: A process for the preparation of hydroxy and amino compounds, in which, in a first step, an aldehyde, ketone or imine is reacted in a Reformatsky reaction with a reactive halogen compound and zinc, in carboxylic esters as solvents, the reactive halogen compound being brought into contact with the zinc at the same time as or after contact with the aldehyde, ketone or imine, and in a second step, the reaction product of the first step is hydrolyzed.

Abstract: The invention relates to a process for the branching of fatty acids or derivatives thereof. More in particular, the invention provides a method for branching saturated fatty acids. This is achieved by contacting a source comprising fatty acids or derivatives thereof, with an ionic liquid. The invention also relates to the mixture of branched fatty acids so obtained.

Abstract: There are disclosed metallic soap fine particles which have an average particle size of 4 .mu.m or smaller and have a content of particles having particle sizes of 10 .mu.m or larger of at most 4% by weight based on the whole metallic soap fine particles; a process for producing the metallic soap fine particles, comprising mixing (a) an aqueous solution containing 0.001 to 20% by weight of an alkali metal salt or an ammonium salt of a fatty acid having 4 to 30 carbon atoms with (b) an aqueous solution or dispersion containing 0.001 to 20% by weight of an inorganic metal salt at a specific temperature to form a slurry of the metallic soap, and drying the resultant slurry at a specific temperature. The metallic soap, which has remarkably fine particles and narrow particle size distribution, is well suited for use e.g.

Abstract: A process is disclosed for chlorinating, brominating and/or iodinating an organic substrate containing both a single acidic hydrogen atom and at least one electron withdrawing group attached to the same carbon atom. The process replaces the single acidic hydrogen with chlorine, bromine and/or iodine and involves reacting the substrate in solution with a halogenating agent (e.g., a perhalomethane wherein the halogen substituents are I, Br and/or Cl, a trihaloacetic acid ester wherein the halogen substituents are Br and/or Cl, or a perfluoroalkyl halide wherein the halide is I, Br and/or Cl) in the presence of (i) a phase transfer catalyst of the formula R.sup.1 R.sup.2 R.sup.3 R.sup.4 LJ where L is selected from the group consisting of phosphorus and nitrogen, where J is an inorganic anion other than fluoride, and where R.sup.1, R.sup.2, R.sup.3 and R.sup.
